AUTOMATIC DRAFT-REGULATING HE ATING SYSTEM.

Specification of Letters Patent.

Application filed May 9, 1905. Serial n). 259,528.

To 00% whom it may 'concern.-

Be it known that I, CASPER FAUST, a citizen of the United States,residing atOshkosh, in the county of Winnebago and State of Wisconsin,have invented certain new and useful Improvements inAutomaticwDraft-Regulating Heating Systems; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable-others skilled in the art to which it appertains tomake and use the same.

My invention relates to improvements in automatic draft-regulatingheating systems; and it consists in the construction, combination, andarrangement of-devices hereinafter described and claimed. I

The object of my invention is to provide an improved apparatus which maybe connected to and included in the smoke-discharge pipe .of a stove orfurnace and which will serve. as a drum to radiate the heat from theheated products of combustion and also to automatically control thedraft, so as 'to preserve aneven temperature. I

In the accompanying drawings, Figure l is a sectional view of anapparatus embodying my improvements, the same being especiallydrum 1 andwhich is provided with sections a Z) for attachment, respectively, tothe pipe 2, which leadsfrom a stove, and to a pipe 3, which leads fromthe said section 1 to the chimney. The said section or drum may be ofany suitable size and may be of any suitable construction. It is hereshown as provided with a supporting intake-cone 4, the lower end ofwhich is closed and which is provided near its lower endwith a series ofopenings 5. upper end of the intake-cone extends into the bottom of thedrum or section 1, is inclined, and forms a seat for a damper 6. Thesaid damperis secured to and is at the lower end a of a vane orbaffle-plate 7, which is here shown as secured to a rod 8, the lower endof the said rod projecting below the said vane or bafiie and beingattached to the said damper. The upper portion of the rod passes throughan opening 9 in the top of the drum or section 1' The and terminates inan arm 10, which is screwthreaded. Said rod is pivotally connected tothe upper portion of the section or drum 1, as at 11, for verticalangular movement to adapt the vane or baffle-plate and the damper forsuch movement. On'the screw-threaded arm 10 is an adjusting andcounterbalancing weight 13.

The weight of the damper and vane combined exceeds that of theregulating-weight 13, so that the damper is normally closed to preventthe admission of air into the drum through the openings 5. The heatedproducts of combustion from the stove pass through the drum or section 1in the direction indicated by the arrow in Fig. 1, the velocity of thecurrent depending on the heat of such products. When the heat of thesame exceeds a certain predetermined degree, the current, by acting tobe admitted to the drum through the cone 4:, hence reducing the draft ofthe stove. As soon as the temperature of the heated products becomeslowered the damper closes automatic'ally by overcoming the weight 13,and

so on, the result being that the vane, damper, and weight-lever 1O coactto automatically regulate the draft.

"In Fig. 2 I show a modified construction of my invention, in which thedrum is provided at opposite sides with connections c d for attachment,respectively, to the smoke-pipe which leads from the furnace and to apipe which leads to the chimney. In this form'of I the invention" thesupporting-cone is formed 75f a plurality of sections telescopicallyconnected together, such sections 14 15 being here indicated. Anysuitable number of the sections may be provided according to therequired height of the drum above the floor.

Not only does my improved apparatus serve to regulate the draft of astove or furnace, and hence eifect an economy of fuel burned therein,butsince the supporting-cone of the drum has its intake openingimmediately above the floor the air which is admitted into the drum isthe coldest air in the room, as will be understood, so that theapparatus serves also to automatically utilize the coldest air in theroom when acting upon the damper.

- From the foregoing description, taken in connection withtheaccompanying drawings, the construction and operation of the inven-IIO intake, a pivoted vane in the drum between the attachments andconnected to the damper, and a counterbalancing-Weight for said vane anddamper.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

CASP ER FAUST.
